[Problem] To make it easy to attach a counterplate to a specified position on a cutting plate, to prevent the counterplate from falling from the punch die during punching, and to prevent the counterplate from making contact with a sheet. [Solution] The present invention comprises: a housing (2) which includes a hole-side inclined part (21), and in which an accommodation hole is formed; a locking means (3) which alternates between a lower lock and an upper lock in the housing (2); and a sliding shaft member (4) mounted to the housing. The inner diameter of the upper side of the hole-side inclined part (21) is larger than the inner diameter of the lower side thereof. The locking means (3) is disposed above the hole-side inclined part (21). In the sliding shaft member (4), the following are integrally formed: a lower inclined part (42) which is disposed above a protruding part that protrudes below the housing (2), and which has the same direction of inclination as the hole-side inclined part (21) and a different angle of inclination thereto; and an intermediate inclined part (43) which is disposed above the lower inclined part (42), and which has the opposite direction of inclination to the hole-side inclined part (21). When the sliding shaft member (4) is pulled downwards and is stopped at the lower limit position, the lower lock state is engaged, and when the sliding shaft member (4) is pushed upwards and is stopped at the upper limit position, the upper lock state is engaged. |
